Other Products

Floss™ is a brand new material for conducting deformation simulations that was developed at the Kagoshima Prefectural Institute of Industrial Technology in order to visually identify the way metal moves as it deforms and the way internal defects form.

Tool Warmer™ can raise the temperature of forging dies prior to usage easily and in a short amount of time, which enables avoidance of troubles that are likely to occur at the beginning of operations.
